Tiny balance update bug after importprivkey #640

   If you import a private key of an address you are already watching and without a rescan, the available balance does not upgrade correctly.

   Steps (regtest):

   1. generate 101
   2. getnewaddress, store somewhere
   3. sendtoaddress <addr-from-2> 10
   4. dumpprivkey <addr-from-2>, store somewhere
   5. Stop node
   6. Remove wallet.dat
   7. Start node
   8. importaddress <addr-from-2> (== triggers rescan) watch only balance should list properly
   9. importprivkey "<WIF-key-from-4>" "test" false will lead to available balance of 0 (but should be 10)

   A restart solves the issue.

   Bitcoind (listtransactions, getbalance, etc.) is not affected.

   Moved from bitcoin/bitcoin#11477.
